an improved mechanism "for rolling; down the folded or interlocked portions or flanges oi contai er parts. v

Another object of the invention is to construct an improved mechanism capable of rollin down. a seam formed around the lateral s .es of a container body.

Other objectsot the invention will be apparent to those skilled in the art to which my invention relates :troni thei'ollowing description taken in connection with the accompanying drawings, wherein Fig. 1 is a side elevation of a rolling down machine or mechanism embodying my invention.

Fig. 1 is a fragmentary section showing the rolling of the seam into final position where the container body isfformed' with a seam receiving recess.

Fig. 2 is a front elevation of the machine.

Fig". 3 is a rear elevation of the machine.

The machine or mechanism embodying the nrsent invention is adapted for rolling into final'torin or shape the seamed portions or flanges of container parts, one example of such parts comprising the container body and one of its heads. WVhere these parts are to be connected the seamed portionsconstitute flanges which have been previously folded or otherwise related, one to the other, so thatwhen tl'iey are rolled down by the ma chine herein. disclosed, the scanned portions.

are compressed or rolled into final position, formin 'a liquid tight, permanent joint. Certain mechanisms and processes of folding and interlocking the flanges of the body and head are disclosed in my aforesaid application; thereafter the container body and adjacent head are positioned on the machine shown herein (see Fig. 1) and then the container rotated to effect therolling down operation, as will later appear.

in the drawings, indicates aframe comtatably supporting a shaft and the latter supporting a rod 59, the purpose 01" which will later be set'forth. At its inner end, the shaft 58 is provided with a gear 60 with which meshes a pinion 61 fixed to a countershatt 62, also mounted in suitable bearings-63 pro vided on the standards The shaft 62 is provided with fast and loose pulleys 64, 65, arranged to be driven by a belt 66. On its outer end, the shaft 58 is provided .with a supporting member 67 having a mandrel 68 on its free end. As shown in this View, the container body A fits over and is supported by the member .67, its head a engaging the mandrel 68. The supporting member 67 may have a diameter approximately equal to the interior diameter of the body or it may be of less diameter and thus be utilized'for use in connection with different sizes of container bodies. I The shaft 58 servesto rotate the supporting member 67 and the lat-terin turn serves to rotate the body due to its engagement therewith resulting from the pressure of a rolling down roller 69 to which reference will laterbe'made. 70 indicates a bracket removably mounted on the free end of the rod 59 with theside wall of the body A. The roller 69 may be provided with a flanged portion 69 which extends inwardly of the folded over flanges, thereby guiding the body as it rotates and preventing its. outward movement and also preventing spreading ofthe seamed flanges outwardly beyond the plane of the head 1. At its upper end, the bracket 70 is provided with a cross head 74in which is formed a screw threaded opening. 7 5 indicates a screw fitting the screw threaded openmg in the cross head and carrying wheel or other suitable device 76, whereby the screw may be rotated. The free end of the screw 75 engages the slide 71 to force it downwardly insure their complete rolling down against the body side wall.

Where the body A is formed with a recess to receive the seam and provide a substantially flush side wall for the completed container, the mandrel 68 is formed with recess 68, as shown in Fig. 1. i

The supporting member may be removably mounted on the shaft 58 so that members having any desired diameter and length may be mounted thereon.

The bracket 70 is held in position by the clamping members 71 71, which may be adjusted longitudinally of the rod 59 to position the seaming device or roller 69 in operative relation to the mandrel 68. The members 71, 71 are adjustably secured to the rod 59 by suitable bolts 70 engaging aligned flanges provided on the opposite sides of the clamping members 71. The rod 59 is adjustably held by the bearings 57 in a similar manner so that adjustment of the roller 69 relative to the mandrel can be effected by adjusting the bracket on the rod 59 or by adjusting the latter endwise in the bearing members 57.

In my form of construction the shaft 58 and rod 59 are relatively long and their respective supports are spaced from each other so that the effective pressure required to roll down the folded seams into final form and condition, even on relatively thick gage metal, will be adequately resisted.

In my form of construction it will be noted that the mandrel is within the container and the rolling down roller is aligned therewith, so that they may co-act to roll the flanges into a seamed joint on or around the side wall of the body; and also that the roller is shaped to co-operate with the mandrel with the result that the body A is held thereon without the use of clamping devices and the folded portions of the seam, or any of them are prevented from bulging laterally or outwardly relative to the surface of the head a.

To those skilled in the art to which my invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the spirit and scope thereof. My disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting.

What I claim is: 1. In apparatus of the class described, the

combination with a frame, of a pair of members supported on said frame in relatively stationary, parallel relation, corresponding ends of said members extending outwardly from said. frame, the extended end of one of said members carrying a mandrel adapted to support a container body and head having their flanges in interlocked relation, means for rotating the mandrel carrying member, a support on the extended end of the other member and provided with guides disposed perpendicularly to the axis thereof, a slide movably engaging said guides, a roller on said slide co-acting with said mandrel for rolling down said flanges, and means for operating said slide.

2. In apparatus of the class described, the combination with a frame, of a pair of members supported on said frame in relatively stationary, parallel relation, corresponding ends of said members extending outwardly from said frame, the extended end of one of said members carrying a mandrel adapted to support a container body and head having their flanges in interlocked relation, means for rotating the mandrel carrying member, a support adjustably mounted on the extended end of the other member and provided with guides disposed perpendicularly to the axis thereof, a slide movably engaging said guides, a roller on said slide co-acting with said mandrel for rolling down said flanges, and means for operating said slide.

in apparatus of the class described, the combination with a frame, of a pair of members supported on said frame in relatively stationary, parallel relation with corresponding ends thereof extending outwardly from said frame, one of said members being rotatable in said frame and carrying on its 6X- tended end a mandrel adapted to support a container body and head with their flanges in interlocked relation and the other member being movable in an endwise direction relative to said frame and said first mentioned member, means for adjustably securing the last mentioned member to said frame, means for rotating the first mentioned member, a

support on the extended end of said endwise movable member and provided with guides disposed perpendicularly to its axis, a slide movably engaging said guides, a roller on said slide for rolling down said flanges, and means foroperating said slide.

In testimony whereof, i have hereunto subscribed my name.
